IMPROVBD SKATE.

TO ALLWHOM`IT MAY (XNCEIU:l

Beit known that I, LVI B. VTYNcr, ofvLoWell, in `the county ofMiddlesex, and State of Massachusetts, have invented new andh usefulImprovements in'SpringSkates; and I do'hereby declare that the followingis a full and exactdescription-thereof, reference being had to theaccompanying'drawings, and/to the letters ot'Vv reference markedthereon..

To enr-.ble others skilled in the art to make and use myzinvention, Iwill proceed to describe its construction and operation.

Figure 1 represents a plan of a skate with `my improvement attached.

Figure 2 represents a side elevation ofv the same. i

Figure 3 represents a longitudinal section through A and B of iig. 1.I

a represents the stock, b the runner, c c the stands, d d the slots, e ethe spring-seats, andffl the springs.

The stock a is made of wood or any other material, formed and finishedwith holes near each end. The stands c e are'made with `the screws z'z'cast in, and grcovedA the thickness ofthe runner. Through these stands cc are holes made for the reception of the screws n n. The screws z' inthe stands`c c are `then placed in the holes in thestock a, and securedby means of the nuts m m. The runner l is made in the usual way, withtwo or more projections jj, their length corresponding with the diameterof the spring-seats e e,`and length of the stands e' c. In each of theseprojectionsjj the slots cl el are made, the distance betweencorresponding exactly with the distance between the screw-holes in thestands c c. Also on these projectionsjj the spring-seats e e are placed.The springs ff made of rubber `or any other material, of any form orshape, are then placed on the stock so asto come directly over thespring-seats e" e.V 'The runner 4b is then placed in position in thestands c c, the

spring-seats e e coming directly over and on thesprings ff,.and ispressed down. The screws n, n are thenf inserted through the holes inthestands ofc and slots d d in the runner b, which securely holdsandfaste'ns them in.

The advantage of this simple device and improvement is apparent, therebeing just suiiicient elasticity and spring to the slcate, at all timesand under all circumstances, tocompletely and entirely overcome therigidity,

imperfect and uneven surface of the ice; thus the skater is enabledto'glide over the ice with more ease and comfort than on the ordinaryspring-skates. Y

What I claim as my invention, and desire to secure by Letters Patent, isA `The combination and arrangement of the grooved stands c c, slots ddLsorews or pins n n, spring-seats e e, and springs f f, substantiallyas and for the purpose herein Aspecitie I L, B. TYNG.
